Synthetic data for maritime autonomy
All-weather, all-sea-state perception data for autonomous vessels, USVs, and coastal surveillance. Generate the rare and dangerous scenarios you can never safely collect at sea, labeled to the pixel across EO, IR, SWIR, and radar.
Working model in one week. Zero sea trials.
The data that matters most is the data you cannot safely collect
Maritime AI fails for one reason above all: bad data. Real collection at sea is slow, costly, and weather-dependent, and it skews to calm, common, benign conditions. The cases that decide a mission, heavy sea states, night, fog, glint, crowded ports, and fast inbound small craft, are exactly the ones you cannot stage.
Stardust generates them on demand. Built on Unreal Engine and a learned rendering stack, it produces sensor-true, fully labeled maritime scenes across the full operational envelope, with EO, IR, SWIR, and physics-based X-band and S-band radar in registration. Closed-loop simulation then lets your autonomy stack act in the scene and be scored against ground truth, so perception and planning are validated before the first sea trial.
Why real data falls short
// collecting at sea today
- ✕Collecting labeled data at sea is slow, costly, and weather-dependent
- ✕The dangerous cases, heavy seas, night, fog, glint, and near-collisions, are exactly the ones you cannot stage
- ✕EO alone misses targets that IR, SWIR, and radar would catch
- ✕Open-loop data cannot validate autonomy: without closed-loop control, perception and planning failures stay hidden until deployment
Sensor-true data, perfectly labeled
EO, IR, SWIR, and physics-based X-band and S-band marine radar, in perfect registration and matched to your fusion stack.
Inside the maritime data
What teams build with it
Speaks your domain
The vocabulary, sensors, and benchmarks maritime teams actually use.
“We hit great real-world performance almost immediately. But even more impressive, Bifrost’s 3D metadata let us develop AI capabilities that just are not possible with real data.”

Questions teams ask
How do you train a USV to avoid collisions without sea trials?
Generate thousands of labeled collision and COLREGS scenarios across sea states, weather, and traffic, then close the loop so the autonomy stack acts and is scored against ground truth.
What sensors do you need for maritime ATR?
EO/RGB, thermal IR, and marine radar in X-band and S-band. Stardust generates all of them with pixel-perfect labels and 3D metadata.
Can you simulate marine radar?
Yes. Real-time, physics-based X-band and S-band radar with configurable carrier frequency, beamwidth, polarization, and antenna pattern, developed in partnership with Ansys and used for radar system validation.
How do you cover the long tail at sea?
Find the gaps and biases in your real data, then generate targeted synthetic data patches to fill them, around 100x faster than collecting more at sea.
What is closed-loop maritime simulation?
A step-through simulation where your autonomy stack observes synthetic sensor frames and issues controls each timestep, so perception and planning can be regression-tested in CI.
